To all whom it may concern Be it known that I, VVILLARD JAY W001)- COCK,a citizen of the United States, and resident of Brooklyn, in the countyof hiings and State of New York, have invented certain new and usefulImprovements in Adjustable Distributors for Internal-Qombustion Engines,of which the followmg 1s a specification.

My invention relates to an adjustable distributer for internalcombustion engine using compressed air or any similar agent.

At the present time there is no distributing disk known to me which hasports so arranged that air under pressure 1S admitted to more than onecylinder at a tune, and three cylinder engines especially are apt tostop in such a position that no port 13 open to admit air, or arrangedso that the engine can be started ahead or astern as desired The objectof my invention is to provide means for admitting air into two or morecylinders of a multi-cylinder internal combustion engine atcertainpositions of the crank circle which will make the rotation thereofpositive, so the engine will start in either direction.

The methodof obtaining these results is illustrated in the accompanyingdrawlngs.

Figure 1 shows a sectional elevation.

Fig. 2 shows the elevation.

Fig. 3 shows anend view. a

Fig. 4 shows a plan of the'p'osition of the ports for the ahead motionwhen crank N0. 1 is on the top center.

Fig. 5 shows a plan of the position of the ports for the astern motionwhen crank No. l is on the top center.

Fig. 6 shows the face of the adjustable disk in position for aheadmotion when No. l crank is on the top center.

Fig. 7 shows the face of the rotating disk in position for ahead motionwhen N0. 1 crank is on the top center.

Reference being made to the accompanying drawings, Fig. 2, Sheet 1, 33,represents the frame which is attached to the engine by bolts passingthrough the holes 36, 37 38 and 39 and contains the bearings 34 and 35and also the chamber 4 F 1g 1 which is bored to receive the rotatingdisk 5 and the adjustable disk 6. The head 7 1s bolted to it. Therotating disk 5 is fast to the shaft 8 as is also the gear 9 whichmeshes in the gear 10, Fig. 4:, which is fast on the crank shaft andtherefore drives the rotating disk at the same speed as the crankshaft,the gears being the same diameter.

The rotating disk 5, Fig. 7 has in this case three ports, 11, 12, and13, which connect with the three cylinders actuating No. 1, 2 and 3cranks set at 120 degrees respectively. These cylinders are not shownand the ports referred to are respectively on the same radius as theports 14, 15 and 16 in the adjustable disk 6, Fig. 6, whose face is keptin contact with the face of the rotating disk 5 shown in Fig. 1, by thespring 17 and also by the pressure of air when it is in service.

In the back face of the adjustable disk, or the face in contactwith thehead 7, Fig. 1, are cut three channels, 18, 19 and 20, Fig. 4:, whichare the same radius as the ports 14, 15 and 16 and furnish free passagefor the air to the outlet ports 21, 22 and 23 in the head, in which arelocated the pipe connections 24, 25 and 26, Fig. 3, which are connectedby pipes to the three cylinders not shown, the arrangement being so wellknown.

The bell crank 16, Fig. 2, is fast to the adjustable disk shaft 27,which is also, fast to the adjustable disk 6 shown in Fig. 1.

' The slotted lever28, Fig. 3, engages the bell crank 46, Fig. 2, and isfast on the rock shaft 29 as is also the starting and reverse lever 30,which engages with quadrant 31, Fig.3, which holds it in position.

In setting the device above described for operation; The crank pin No.1, Fig. 4, is placed on the top center, and the port 11 Fig. 7, whichadmits air to No. 1 cylinder is set line 4;? to line 18, with the port14; in the adjustable disk 6, Fig. 6, when in this position, as shown inFigs. 4, 5 and 7 air is admitted to No. 1 cylinder during 130 degrees ofthe crank circle.

The cranks are set at 120 degrees, and after moving this distance in thedirection indicated by the arrowhead the port 12 Fig. 7 is then line andline with the port 15 Fig. 6 and No. 2 crank will be on the top center,and during the following 10 degrees of the crank circle the air is onNo. 1 and 2 cylinders, or in other words No. 1 crank pulls No. 2 crank10 degrees past the top center before air is cut off No. 1 cylinder dueto the line 19 of the port 11 passing by the line .50 of port 1% in theadjustable disk 6.

The same action takes place on all the crank pins as they pass the topcenter and therefore the action of the device is positive, and theengine will start with the cranks in any position.

The reverse motion is accomplished by moving the lever 80 to the asternposition 4.0, Fig. 3, which moves the ports 14, 15 and 16 in theadjustable disk 6, Fig. 6, to the opposite end of the port 11, Fi 7, andshown 1n position as described in Fig. 5. The device is now set asbefore explained with No. l crank pin on the top center which has notbeen In ved during this maneuver.

After the setting has been correctly made the position of the crank pinsis of no con- 7 sequence; the engine does start at any pomt in eitherdirection according to the position of the starting and reverse lever30, but when this lever is set at 42, Fig. 3, no air passes out of thepipe connection 24-, 25 and 26, although the supply air is admittedthrough the supply pipe 32, because the bridges 43, 44 and 45, Fig. 6,and alsoshown I at 43, Fig. 1, cover the outlet holes 21, 252 and 23 inthe head 7, Fig. 5, thus causing the engine to stop when operated by airunder pressure, or other similar moving agent. 7

The grooves 18, 19and 20 in the adjustable disk 6, Fig. 6, arecontinuous from the ports 1d, 15 and 16 to their respective ends, asshown on the drawing, and provide a free passage to that extent, passingunder a sec tion of the face of the adjustable disk that is in contactwith the head 7, Fig. 1, forming the bridges a3, a4 and 45, which closethe ports 21, 22 and 23 in the head 7, F 5, and also shown by 43, inFig. 1, when the lever 30 in Fig. 3 is placed in position 12 on thequadrant 31.

Having thus described my invention, what I claim as new is, V

1. In an internal combustion engine, a distributer disk or valve havinga port or ports,

and in contact with an adjustable disk valve or member having a port orports with a connecting groove or grooves to provide a free passage tothe port or ports in a stationary "member'with which it is in contact,and

which has outlet openings, the said disk valves or members being incasedand provided with an inlet opening and means provided to keep thesurfaces in contact.

2. In an internal combustion engine, a distributer disk or valveprovided with ports, and which is in contact with an adjustable diskvalve or member provided with ports and grooves, and which is also incontact with a stationary member having ports and provided with outletconnections, the ports being so arranged hat two or more outlets haveopen passageway at the same time from the source of supply, the saiddisk valves or members being incased and provided with an inlet openingand means provided to keep the surfaces in contact.

3. In an internal combustion engine, a distributer disk or valveprovided with ports and which is in contact with an adjustable diskvalve or member provided with ports and grooves, and which is also incontact with a stationary member having ports and provided with outletconnections; a valve seat to obstruct the passage from the source ofsupply to the outlet connections by placing the adjustable disk in adefined position, the said disk valves or members being incased andprovided with an inlet opening, and means provided to keep the surfacesin contact.
